Protection
Maximising the Lifecycle of Your Critical Assets
Polesaver Rot-Guard™ is a proven, ground-line barrier product which protects steel utility poles from the damaging effects of corrosion.

Our innovative, eco-friendly barrier reduces moisture and prevents corrosion, significantly increasing the lifespan of poles while also reducing maintenance costs. Easy to apply and built to withstand harsh environmental conditions, Rot-Guard™ offers proven protection against corrosion, ensuring your infrastructure remains secure and cost-effective for years to come.

Corrosion and its Impact on Infrastructure

Galvanised steel utility poles are strong but vulnerable to ground-line corrosion from moisture, oxygen, soil acidity, and road salts. Harsh environments, like coastal or high-humidity areas, accelerate this damage, leading to costly maintenance, failures, and safety risks. Left unchecked, corrosion shortens pole lifespan, increasing replacement frequency and costs.

Polesaver Rot-Guard™ sleeves prevent corrosion thanks to their durable, dual-layer seal that's created on application. This seal is airtight and waterproof, blocking corrosive elements and preventing rust and corrosion around the ground-line. This proactive protection keeps steel poles structurally sound for decades, reducing maintenance costs and ensuring safer, more reliable utility networks.

Why Choose Rot-Guard™?

80% of steel utility pole failures are due to ground-line corrosion.
Polesaver Rot-Guard™ sleeves protect this vital section of the pole, offering lasting protection for critical infrastructure. 
No Painting Required
Polesaver Rot-Guard™ sleeves negate the need to paint or add extra layers of protection to steel poles, saving production time, cost and resources required.
Substantial cost savings
Rot-Guard™ Sleeves are competitively priced and offer substantial cost savings through maximising the life of the pole, reducing the requirement for inspections, pole remediation and replacement.
Improves Safety
The application of a Rot-Guard™ sleeve ensures poles maintain strength, this improves safety for inspection teams, and for the general public.
Prevents Steel Pole Failure
Polesaver Sleeves prevent corrosion, one of the largest reasons for steel utility pole failure

RFID Built In As Standard

All Blaze-Guard™ sleeves feature RFID (radio-frequency identification) tags as standard, making asset management easy.

EASY APPLICATION IN ANY LOCATION

On-site training, application videos, and an easy-to-use product combine to make Polesaver Rot-Guard™ sleeves a natural choice whether applying them on-site, in the field, or at a pole yard.
Wrap Around
Polesaver Rot-Guard™ sleeves are non-toxic, composite barrier. They wrap around the ground-line section of a steel utility pole.
Heat Apply
When heated, the inner liner melts, and the outer sleeve shrinks down tightly onto the pole to create the Dual-Layer air and watertight seal to the pole surface.
Activate Dual-Layer
The Dual-Layer air and watertight seal excludes all the factors necessary for corrosion to occur at the ground-line section of the pole.
Polesaver Rot-Guard™ sleeves meet the requirements of a number of international standards such as BSI EN252 & SABS Barrier Protection Systems
Polesaver’s dual-layer barrier technology is independently tested and proven by the BRE, Europe’s largest timber test organisation.
